Embodiments provide novel imaging members used in electrostatography. More particularly, there is provided flexible electrophotographic imaging members which exhibit an extended functional life. These imaging members include an improved protective overcoat layer comprising: (1) a polymer blend of a low surface energy copolymer and a chemically resistive copolymer, (2) a chemically resistive copolymer and a slip agent, and (3) a chemically resistive copolymer and the dispersion of a low surface energy Polyhedral Oligomeric Silsesquioxane (POSS) nanoparticles to effect surface contact friction reduction for enhancing wear resistance and for suppressing copy printout defect caused by chemical attack. |
